I decided to modify my Zonestar z9m2 printer because the core yx system I had was not comfortable for me. I opted to disassemble everything and put together a prusa bear. The Zonestar printer, having a single motor for the Z axis, was designed with a belt and pulley system for tensioning. I decided to keep the same system using the same bearings and the same belt keeping the 2040 bosch profile system
This model is designed for KL08 bearings (3 units in total) that allows to hold the acme rod so that it does not move up and down in the movement of the system. Use 2 M5x40mm screws 625z bearings (2 units total) with washers and spacers. For the 2040 frame and piece use m5x10mm allen bolts and square nuts.
